Basically, China Unicom’s contract means that whether you sign or not means whether you are with China Unicom or not, eh. Specially appointed. Go buy a mobile phone with a contract phone, because you have to ask the person who sells the mobile phone, do you think your phone is a contract phone? If you ask him, he will tell you that if it is a contract phone, you have signed a contract. If it is not a contract phone, if you just buy a mobile phone, it is not a contract phone. Another point is that when you buy a phone card, whether you sign or not and whether you sign the contract paper means whether you are in the contract.
